The well known leaking radiator issue that has leaked into the transmission and has destroyed my transmission. Both must be replaced. But of course it is beyond the warranty covered dates. Since this is a known issue. It should be covered 100%, shame on Nissan for ignoring the issue. When sites are posting "avoid at all cost", should become a federal investigation. I will not purchase another Nissan.

The contact owns a 2005 Nissan Xterra. While pulling out of the driveway, the vehicle surged, hesitated, and lost acceleration. The vehicle was towed to an independent mechanic where it was diagnosed that the radiator fluid was leaking into the transmission and the transmission needed replacement. The contact also stated that a humming noise was present for approximately three months every time the vehicle was driven. The manufacturer was notified of the failure. The vehicle was not repaired. The approximate failure mileage was 66,000.

A crack in the radiator occurred allowing coolant in to the transmission mixing with the transmission fluid causing catastrophic failure of the transmission. Thankfully, the car was parked and would not start. However, we did "jump" the starter and the car crept home with very little acceleration capabilities.

I purchased this car used from a dealer with approx 64,000 miles. After 2 days and less than 200 miles the car started shuddering as if I was driving over rumble strips and the check engine light came on. The next morning when I went to take it to the dealer there was a horrible rattling sound coming from under the hood that softened as the car warmed up. Needless to say that both of the more common complaints about this car raised their ugly heads at the same time: Transmission and timing chains!! I took it to my local Nissan dealer for evaluation and repair and was told that the cost would be between $8-9,000. Thank god for aftermarket warranty. Anyway... if Nissan does not intend to issue a recall, there should be a disclosure on carfax/autocheck/etc for these significant problems.

Radiator fluid leaking into tranmission

- Beaver Falls, PA, USA

Transmission was rebuilt when I was unable to get it into reverse, costs $3850. A few days after work was done the vehicle starting running rough. Mechanic checked it out and let me know that transmission coolant line in the radiator was allowing coolant to get to the transmission and this voided any warranty on the transmission that he had given me and now the transmission as well as the radiator needed to be replaced. Since this happened, thru some research I see im not the only one and besides the thousands of people that have been ripped off be this obvious defect I'm sure there are at least twice as many that didnt bother to voice a complaint, due to the fact that nothing has been done, nor does it look like anything will be done about this no matter how obvious it is that there should of been a recall. I can only assume that someone or maybe more have been compensated to ensure this issue wasnt pursued by anyone that could make a difference.

Suddey I found my heat not working. Strange, I was low on coolant and no visible leaks. While researching this I came across all the complaints of transmission failure due to the defective welds on the atf cooler within the radiator. I immediately went to dealer and had everything checked out and pressure tested for leaks. They said all is fine and tested ok, we have no idea why you would be low on coolant. Mind you, at this point there is 79K on the odometer and we all know Nissan lame warranty extension is useless due to the convenient mileage cap completely and obviously is in their best interest. Appalling and 100% a safety issue and complete negligence. In an effort to be pro active I ordered an aftermarket radiator and installed it myself. I also flushed and refilled tranny fluid. I am now about to break 100K. I'm now worried about the timing chain issue Nissan also doesn't want to deal with. Anyone reading this should be pro active and change out your radiator and flush your transmission immediately, it's all you can do right now to prevent a bigger issue. It also cost me $400 to do myself. The quote from the dealer was $1500. Good luck to all, I argued and called and called and Nissan could care less and wouldn't even consider any help whatsoever. This was my wife and I's 5th Nissan. Never again!!!!!!

Transmission fail due to defect in transmission cooling tank housed inside the radiator.

After a year of ownership at approx.. 108000 miles, the vehicle would not start. Had it towed to reg. Garage and subsequently another garage with better diagnostic system as the code would not hold/replicate easily. Code was for ECM, which was repaired at owners cost (unaware of recall). There was mix of antifreeze/oil due to leak in radiator. Flushed system and replaced radiator at owner's cost. Within weeks, vehicle was not accelerating correctly and code showing emissions issue and catalytic converter issue. Looking at thousands of dollars in repair costs which appear to simply be a band-aid until the issue begins again. Still paying on the vehicle and a new mom of twins. Now stuck with an unsafe vehicle riddled with repair costs for an issue that Nissan is well aware of and should have fixed. How frustrating that this issue is still in limbo after 2 years, how this cannot be seen as a constantly recurring problem which is extremely unsafe and be the responsibility of Nissan is beyond me. These issues occurred while in motion on a major highway and on side roads with hills.

Radiator defect causing atf fluid to contaminate the transmission, leading to transmission failure, with extensive repairs, and extreme associated costs. This commonly known defect causes transmission to fail while driving, which can be a serious safety issue, and necessitates a full recall!

Transmission has failed at 135,000. Fuel gauge does not work.check engine light stays illuminated, therefore I am unaware of any additional issues, and cannot pass emissions in atlanta, ga, therefore I cannot renew my tag.

I purchased a 2005 Nissan Xterra. The vehicle's transmission is gone due to a fault in the manufacturing. This could have been a potentially dangerous situation - but luckily for me I was not driving or on the highway. I have contacted Nissan regarding this issue and was told that they are not going to assist me in repairing the problem because the vehicle warranty has run out. I bought this vehicle used - the dealer never mentioned anything about a recall or problem at the time that could be fixed by Nissan nor did I receive any correspondence from Nissan themselves. Now I am stuck with the financial burden of $5000 for the repair. I don't think this is fair - the used car dealers should be mandated by law to fix vehicles with recalls and inform car buyers that there is a manufacturing defect. Nissan also should be held accountable.

- Leominster, MA, USA

Catastrophic transmission failure as a result of radiator fluid leaking into the transmission allowed by a design defect in the transmission/radiator. Had to pay $5,158 to fix this problem. Manufacturer seems to take no responsibility for this design defect when failure occurs over 100,000 miles. This is wrong.

- Brush Prairie, WA, USA

Engine coolant infiltrating in to the transmission which causes both the transmission and radiator to fail. Estimated cost to replace these items is approximately $4500. This problem happens and corrodes the valves, gaskets and seals. In my case will driving the vehicle the transmission completely failed causing the vehicle to be stranded on the side of the highway for 2 hours while a tow truck was enroute.

Radiator has transmission fluid in it. Transmission has radiator fluid in it. Will have to replace both. App, $5000. Vehicle shifts hard then stutters, vibration

- Pace, FL, USA

Radiator fluids leaked into tranmission causing failure. This is a known problem on these vehicles and Nissan has not recalled them. They were in a class action lawsuit in 2012.

I bought a used Nissan Xterra last year that had 100K mile. Traveling from work warning lights come on. I took my vehicle to meineke for diagnostic. The warning code read transmission. Took it to the Nissan dealer knoxville tn the next day and tech diagnosed problem as a failed transmission fluid cooler located in the radiator assembly that allowed coolant to mix with and contaminate the automatic transmission fluid, resulting in damaged internal transmission components and a damaged internal transmission computer. That week my car produced slowing of vehicle and times where engine would not crank. I ended up paying $3010.35 (attached) to chip's transmission to get fixed. I contacted Nissan North America regarding the issue and was provided documentation that after reviewing my case; they were unable to offer financial assistance because the vehicle was outside the new vehicle limited warranty. (attached) I found out a class action lawsuit was filed regarding this matter and the fix was an extended warranty. Per document if you miles were over 90K miles you were out of luck. Well luck plays no part in this matter as I had bought this vehicle used over 100K miles and was never notified. I had a warranty for 1 yr or 12000 miles when I bought was never notified. I feel like regardless of the mileage. This was a defective part that was installed by Nissan dealership and was a known problem by consumers. This part should be replaced or recalled by Nissan and that an ongoing investigation on the behalf of those consumer who had these vehicles should not have to pay for such extensive repairs or damages being that it is Nissan's wrongful intentions. I have had to eat the cost of not only missing work but paying for rental car expenses for 14 days (attached) plus the parts/repair to this vehicle. F you would like to contact me regarding this matter.]
